o. The discal and postdiscal spots on the hindwing beneath are situate close together and 
almost form parallel arcuate rows. Costal spot of hindwing above posteriorly extended. 
Fringes of the wings above with distinct light spots. PA. molomo. 
oo. The discal spots on the hindwing beneath as usually form a very irregular row not being 
parallel to the postdiscal spots. Costal spot of hindwing above transverse or absent. 
1. Discal spots of hindwing beneath filled up with whitish. Fringes of the wings broad, 
above spotted light. PA. damarensis. 
2. Discal spots of hind wing beneath small and black. Fringes of the wings above without 
distinct light spots. PA. marshalli. 
§§. Both wings above only with a fine dark marginal line which is only expanded at the apex 
of the forewing. Ground-colour beneath light greyish-brown with discal spots filled up with 
whitish. PA. simplex. 
[3. Forewing above with a broad dark costal-marginal band reaching to the base or at least to the basal 
third, or entirely blackish. <$. Forewing almost triangular with an almost straight margin. $. Fore¬ 
wing longer and obtuser with a very much bent margin. 
*. Basal half of hindwing above at least in the areas 1 c to 3 or 4 and 5 yellow or reddish-yellow. 
Forewing above very extensively yellow or reddish-yellow. 
§. Discal spots of hindwing beneath at least between the veins 1 a and 5 united into a broad 
whitish-grey transverse line. PA. thyra. 
§§. Discal spots of hindwing separated though contiguous. PA. almeida. 
**. Hindwing above at least beyond the middle blackish-grey or blackish. Forewing above quite 
black or only with a yellow or whitish discal area or postdiscal band. 
§. Hindwing beneath of a bright rosy-red ground-colour and separate or almost separate, light, 
sometimes indistinct discal spots. PA. conradsi. 
§§. Hindwing beneath with a grey, yellowish, or brownish (never red) ground-colour. 
1. The postdiscal spots of the forewing beneath uni-coloured black. Forewing above with 
or without a yellow spot in the centre [in (1 b) 2, 3 (4)]. Hindwing above invariably with 
a large orange spot at the margin in the areas 1 c to 3 (to 5) and with black marginal dots 
between the veins. PA. pier us. 
2. The postdiscal spots of the forewing beneath at least in 1 b to 3 with a silvery dot. Comp, 
here also PA. damarensis var. ■—- $. Forewing above without markings or with a whitish 
subapical band, or in the centre feebly lighter yellowish; hindwing above uni-coloured 
without markings or with a dentate whitish or yellowish submarginal line. In the $ the 
forewing generally exhibits a light (whitish or reddish-yellow) postdiscal band and the 
hindwing a similar marginal band or line enclosing black marginal dots. 
a. rj\ Hindwing above with a yellowish submarginal band. $. Hindwing above with 
a broad orange marginal band enclosing separate black marginal dots. PA. laikosama. 
b. d'. Hind wing above uni-coloured blackish without markings or only with a dentate 
grey, indistinct submarginal line. $. Hindwing above with a dentate, yellowish sub- 
marginal line. PA. orthrus. 
II. Margin and fringes of hind wing margined all round. Hind wing at the anal angle fully rounded without 
an angle or lobe. Wings above with a bluish-white ground-colour. PA. barklyi. 
Ph. wallengreni Trim. Forewing above black, at the costal margin almost to the apex orange-yellow 
and with a large similar one of the posterior margin covering the base of the areas 1 b to 4 and the posterior 
longitudinal half of the discal cell; the black colour thus forms a broad, midway narrowed marginal band, 
and between the costal margin and the spot of the posterior margin it proceeds as far as the base like a proxi- 
mally pointed longitudinal stripe; hindwing above orange with a black marginal band which is very broad 
(about 5 mm) at the costal margin and, behind vein 4, rapidly tapers off into a marginal line; the base is darkened 
in a width of about 3 mm; on the under surface the hindwing as well as the apex and marginal band of the 
forewing are yellowish or reddish brown with numerous silvery spots. The ^ is lighter and otherwise differs 
above by the yellow spot of the posterior margin of the forewing being continued as a narrow submarginal 
stripe as far as vein 6 or 7, and by the yellow colour of the forewing being divided by a dark postdiscal nebulous 
band into a discal and a submarginal part. Gape Colony.
